Premature placental separation is which obstetric condition?

• A. Placenta Previa
• B. Ectopic Pregnancy
• C. Abruptio Placenta
• D. Prolapsed Cord

Answer: (C)

Premature placental separation, or placental abruption, is when the placenta detaches from the uterine wall before the baby is delivered. This disrupts the exchange of oxygen and nutrients, causing vaginal bleeding and uterine contractions, and it can lead to fetal distress or loss if the detachment is significant. Painful bleeding with a tender or firm (sometimes rigid) uterus is a common clue, and the situation may involve concealed bleeding where there isn’t much external blood loss. Risk factors include high blood pressure, trauma, smoking, cocaine use, and advanced maternal age.

Diagnosis is mainly clinical; ultrasound can help but may not rule out abruption, since bleeding can occur behind the placenta and not be visible on imaging. Management centers on stabilizing the mother with IV fluids and blood products as needed, continuous fetal monitoring, and delivering if there is ongoing bleeding, maternal instability, or fetal distress. In contrast, placenta previa causes painless bleeding with the placenta over the cervical os; ectopic pregnancy is implantation outside the uterus; and prolapsed cord presents with sudden fetal distress and a protruding umbilical cord. The scenario described aligns with placental abruption.
